When using PowerShell 7 built on .NET Core 3.0:

1 | less
q # to quit

Now use the UpArrow key to go back in history

Expected:

1 | less  #since this was the last command

Actual:

nothing, as PSReadLine receives `<ESC>A` (as two key presses) which is the VT100 escape sequence for up arrow

This repros on macOS and Linux. If you use PowerShell Core 6.x (same version of PSReadLine is included) this doesn't repro as it's built on .NET Core 2.1.

Interestingly, if you use:

"`e[2J"

This is the VT100 escape sequence to clear the screen, then the up arrow returns the correct key to [Console]::ReadKey() again instead of the up arrow escape sequence.
This will block the PowerShell 7 release. PowerShell/PSReadLine#1007
